[Help] Moog Source keys intermittent

Hey there,

my Moog Source has three keys that seem intermittent. Notes sometimes be triggered double and pitch sometimes goes wonky on that key.
Any hints how I can repair the keys contact inside the Source?
I know my way around in electronic devices and have the Source opened on occasions to clean it and to fix the Crazy Source problem.
Are there replacement keyboards?

Thanks for your advice,

I have a large box of original Source keyboard contacts. Most are NOS (new old stock.)
If you can identify which section(s) are beyond repair, I can provide ones to replace them with.

Are they swapped in sets of octaves? So that there are 3 octave sections plus a single key?

I’m considering swapping all keys, for I guess it is just a matter of (short) time until things start to act up more.

What would be my repair options if I don’t swap, besides cleaning? Nothing much I guess?

Thanks,
dual


ps. I’d appreciate if you could take a quick look at the other topic, I’m about to post.
